Be it known that I, ADoLPH HnnPoLsHEI MER, a citizen of the UnitedStates, residing at Seward, in the county of Seward and State ofNebraska, have invented a new and useful Train-Pipe Coupling,of whichthe following is aspeciieatio'n.`

My invention relates to careouplers, and has for its objects to producea device of this character which will be simple `of construe tion,Vinexpensive tomanufacture and apply to any cars, eiicient inoperatiomandwhich will automatically4 couple and uncouple both thecarsandthe train-pipe.V

To these ends the invention comprises, in a train-pipe coupler, the4combination, with a sliding member, of a spring tending to projectsaid., member outward, aV cooperating member adapted to force saidmemberinward against the actioniof the spring, and a rotatable valveadapted to be opened when said member is moved inward and to be closedwhen moved outward.

The invention further comprises the details of construction andcombinationof parte more fully hereinafter described. v

In the accompanying drawings, Figure 1 is a side elevationillustratingtwo cars coupled by my improved device. Fig` 2 is a similarview of the coupler on an enlarged scale.`

Fig. 3 is a horizontal sectional plan illnstratn ing the internalmechanism of theeoupler.

Fig'. 4 is a horizontal sectional elevation through the headof thetrain-pipe-conplin'g Ass `member to show the valve and its operatingmeans. i

. Referring to the drawings, 1 and 2 indicate two membersof the couplerattached each to the adjacent or meeting end of two-ears in' the usualor any desired manner to couple or uncouple'the same, as in Fig. 1. Asthe con-` struction and operation of the two members of the couplerareidentical in every particularexcept the changein position of theparts whereby they cooperate, I will describe in de tail but one member,in which* 3 indicates the shank of the coupler, provided with a head 4,recessed as usual,` as at5.

(i is a movable jaw pivote'd in the head'bn vertical axis 7, upon whichit isadapted to 'swing freely tocoupleor uncouple the cars, as presentlyexplained. `The jaw is provided with an integral finger 8, which liesnormally within a socket 9, formed in the interior of the head toreceive the same and the jaw-op- .erating mechanism.`

`1-10 is a horizontal lever mounted onthe top face of the coupler-headand-extending outward tothe side of l the carin position to be readilyoperated by the attendant withouthis having to pass between the cars.This lever may, through suitable connections, be operated` fromA the topof the car,if so de sired. ,The lever is mounted upon the end cfaverticall `pivot 11, .journaledin the couplerJhead. f Fixed near thelower end Vet' the pivot within the socket Qandadapted to `lugsdepending vertically from the under The rod16 carries a sideof theear-coupler. coupling-head 19, recessed at 20 to form a `horizontalprojecting portion or arm 21.

V22 is a rotatable horizontal valve `mounted in the arm 2l, the end 'ofthe valve being ,l

iiush with the inner face of the said arm `and its outer end beingiixedly attached to a crank-arm 23, by which the valveis rotated, aspresently described. The valve is provided With a central horizontalair-passage 24, open at its outer end, or that endwhich registers withthe valve in the cooperating pipe-coupling member, but closed `at itsinner end.

25 is an air-passage formed through the wall of the valve and adapted toestablishV communication between the passage 24 and a passage formedthrough the nipple 26, to 9 which the end of the train-pipe isattaCbed.27 is al tongue or key formed on` the inner face of the valve, by whichit is locked to the valve carried by the cooperating member.

28 is a rigid horizontally-projecting arm be tightened in its seat, and33 is a lbearing for the set-screw.

In coupling two cars the following action takes place: Supposing themovable jaw 6 to occupy theposition shown in dotted lines in Fig. 3, thecars coming together will automatically throw the jaw inward, causingits finger 8 to engage the recess 1 4: in link 13e moving the sarnetothexposition shown .in full' linesythu's locking the parts. At the sametime the member of the train-pipe couplei'will be automatically forcedinward by the lcoasting member on-the adjacent car against the action ofspring 39, thus causing the crank-arm to rock on its pivotl28a androtate the/valve. 22. This rotation of the valve brings he airpassage inthe wall' of ihe valve Iinto? register with the air-passage in tbenipple26 and at the same time locks the valve tothe valve in thecooperating-members and establishes communieation with the'pipe-sectioncarried thereby. To unconple', it is only necessary for thebrakeman to." move leverO to' release the ngel-8 ofthe.-

the ears toseparate, this jaw -5 and ypermit separation of the earsallowing the spring tol project said member outward,

when moved outward.

move the pipe-coupling memberoutward and operate the Valve in a mannerreversely to that above described.

It is to be understood that I do net limit or confine myself to thedetails herein shown and described, as such changes therein as wouldsuggest themselves to the skilled mechanic may be made without departingfrom the spirit or scope of my invention.

Having thus described my'invention, what I claim is- 1. in a train-.pipecoupler, the combination with a sliding member of a spring tending to acoperating member fadapted to force said member inwardagainstjthe actionofthe. spring and a rotatable valve adapted to vbe opened when saidmemberis moved inward and to be closed 2.1 In a train-pipe coupler, thewith aslidingmember of a spring tending to project said member outward,'a coperating `member adapted to .forcesaid member'in'- wardagainst the'action of the spring, ai ro tatable valve carriedby said meinben and acrank-arm pivotally connected tothe coupler, and adapted tion when themember is forced inward and to close the valvewhe'n the memberis 'movedoutward.
